标题 :Catalytic oxidation of alkyl-substituted hydroquinones to the corresponding p-benzoquinones
发明人：KUTEPOW NIKOLAUS VON; MAGIN AUGUST; JOSCHEK HANS-INGO
权利人:BASF AG
摘要:AIR OXIDATION OF ALKYL-SUBSTITUTED HYDROQUINONES IN THE PRESENCE OF HEAVY METAL SALTS AS CATALYSTS IN A LIQUID MIXED PHASE CONSISTING OF AN AQUEOUS PHASE AND AN ORGANIC PHASE. THE AQUEOUS PHASE CONTAINS DISSOLVED CATALYST AND ADDITIVES FOR SETTING UP A PH BELOW 7, AND THE ORGANIC PHASE IS A SELECTIVE SOLVENT FOR THE ALKYL-SUBSTITUTED PBENZOQUINONE FORMED IN THE OXIDATION. THE PROCESS ENABLES 2,3,6-TRIMETHYLHYDROQUINONE, AN IMPORTANT INTERMEDIATE IN THE SYNTHESIS OF VITMIN E, TO BE SEPARATED FROM MIXTURES OF METHYL-SUBSTITUTED HYDROQUINONES.

摘要:The present invention relates to resin compositions for radical curing comprising a component (I) containing reactive carbon-carbon unsaturations and a component (II) containing XH-groups, with X not being C or O., which resin compositions (a) are substantially free of photoinitiators; (b.) have an average number of reactive carbon-carbon unsaturations of component (I) equal to or higher than 2; (c) have an average number of XH-groups of component (II) equal to or higher than 2; (d) whereby at least one of the average numbers of (b) and (c) is higher than 2; (e) and at most 5 mol% of the reactive unsaturations is capable of undergoing homopolymerisation; (f) respectively is present in the form of a mono-ene functional alkylene; and (g) the molar ratio of the XH-groups and of the reactive unsaturations is in the range of from 4 : 1 to 1 : 4. < >The present invention also relates to processes for curing such resin compositions, in particular by cold curing. And finally, the present invention also relates to a new process for the synthesis of Diels-Alder adducts of cyclopentadiene and a resin component containing telechelic carbon-carbon unsaturation. < >The resin compositions are capable of providing constructive materials with tack-free surfaces by fast, and tunable, radical curing, and without any problems of so-called oxygen inhibition. Suitable applications are in chemical anchoring, roofing, flooring, (re)-lining, SMCs and BMCs.

摘要:The disclosure generally relates to compositions and methods for the production of nucleic acid molecules. In some aspects, the invention allows for the microscale generation of nucleic acid molecules, optionally followed by assembly of these nucleic acid molecules into larger molecules. In some aspects, the invention allows for efficient production of nucleic acid molecules (e.g., large nucleic acid molecules such as genomes).
